Nuclear Fusion Reactor Achieves Net Energy Gain for 100 Hours

In a milestone that brings commercial fusion power closer to reality, a tokamak reactor operated by Commonwealth Fusion Systems has maintained a net energy gain for over 100 continuous hours???shattering the previous record of just 5 seconds.

What This Means

The reactor produced 11 megawatts of power while consuming only 2.5 megawatts to sustain the fusion reaction???a Q-value of 4.4. This demonstrates that fusion can be a viable, sustainable energy source.
